Similar numerals of reference designate corresponding 'parts in vall of the views of the drawings.V

I would have 1t distinctly understood that my novel deviceis formed of a material thatfwill not break should it fall, upon a hard'surfacejand contains no parts such as bearingsthat'are likely to get out of erder after a short period'of use, and it comprisesan arm 1, of channel'orm in cross section, and at its outer end 2, said channel is constructed so as ,to form a solid 'piece for an important purpose hereinafterset forth,4 f The arm 1, is provided slightly below GEORGE E: soHUnMAN, or PITTSBURGH, rENnsYLvANIa. j'l

j Another. feature of the invention is the' novel arrangement of elementsVv whereby the `With1the foregoing in mind,- the inven- `tion will be fully understood from the Jol- .N STM-ES 'PATENT formen;

the starting point'ot' the head 42,'with arm 3,.

Vhaving hooks A and said hooks or .tongs are secured to the arm l-,byya through and through bolt '5. l" its inner end the arm' 1. '11s provided with. a series of openings The arnr 1, is const'xueted similar to arm l, with the exception that-it is slightly lougerand is void of openings G. lt has like arm 7 the head 2, arms 3 and through and through bolt The. said arm 7` has a strap S secured by a bolt 9 to its inner end I and at 10 the arm is provided with a keeper.

At a point opposite the channel of arm` 7, l'fulcrum a lever'll havinga knob or p roJectlonlQ, said lever beiner secured to the ar1n'7 by a'double-hcaded bolt 13; At

its upper end the lever l1 is bent upwardly as indicated by 14 and below said upwardly extending bend, l provide a' slot 15 as clearly4 show-n 1n Figs. 1` 2 and f It will .bea'ppreciated by referencev to,

the drawings, that; when it is desired to' adjust the arms land 7 for use, it is simply necessary to pass theinner endv of arm 41, through the Strap 8. The hooks 4. of one arm are then placed on either side oi' a. rim. about twelve inches from the split thereof and the `hooks of the opposing arm are then placed directly opposite the first set of hooks and .in the same manner on tbe rim. The lever 11. is then extended to-its full length and the knob or pin 12, is forced into the nearest openingr G, of arm 1. lt isthen simply necessary to break the joint and force the lever 11, downwardly as in` dicated by arrowsiu Fig. i. until it rests soY parallely with knob 7. T he" keeper l0 isv 'then adjusted as te rest in slot 15, and

when this has beenaccomplished the rim will he forced inwardly from the tire shoe or casing (see Fvg. 3) and 'held in a safe andsecure posti4 n. lWhen the inner tube has been placed' 1n the casing and the same has been replaced on the rim` the pin is forced into the next opening oiarm 1, and by reversing-the movement of the lever the rim will eripandilntil it rests in its normal position.

It will be appreciated from the foregoing` that because of the actthat the arms 3 are tion of members 111ml 7 it will he ,nppr'e ciated that seid members are 'more able to4 stand pressure than were they constructed of 'e solid piece of iron.

Having described my invention, what I laim and desire to secure by Lett-ers Iat- In'- a tire rim remover, the combination of anarrn', hooks secured to one end thereof, openings in' the 'opposite end thereof* l :L second arm, hooks secured to one end thereof, a, strap in which the` first-named erm may slide secured at the' end opposite to thalt in which the hookszlre secured ,in
